Advances in Nanotechnology-Based Topical Delivery Systems for Skincare Applications

The growing demand for effective skincare products that can effectively target specific dermatological concerns has accelerated the development of advanced delivery technologies. Among them, nanocarrier-based topical delivery systems have gained significant attention for their ability to enhance the performance of skincare formulations. Acting as versatile delivery tools, nanocarriers not only stabilize and protect sensitive cosmetic ingredients but also improve their penetration through the skin barrier and enable controlled, sustained, or targeted release. Therefore, this review focuses on the recent achievements of nanocarrier-based topical delivery technology for skincare applications, which systematically summarizes the design principles, mechanisms and functional characteristics of diverse nano-based delivery platforms, including vesicular nanocarriers, lipid-based nanocarriers, emulsion-based nanocarriers, polymeric nanocarriers, inorganic nanoparticles, and inclusion complexes. Meanwhile, these nanocarriers are discussed according to their relevance to the pathogenesis of prevalent skin disorders, highlighting how tailored nanocarriers can address specific therapeutic or cosmetic needs. Overall, this review emphasizes the emerging trends and future perspectives of nanotechnology-based topical delivery systems in modern cosmetology, offering more opportunities for precise, effective and science-driven cosmetic solutions.
